Compare any two graphics cards:
GeForce GTX 660 vs Radeon HD 7850
IntroThe GeForce GTX 660 makes use of a 28 nm design. nVidia has clocked the core frequency at 980 MHz. The GDDR5 RAM runs at a speed of 1502 MHz on this model. It features 960 SPUs along with 80 Texture Address Units and 24 Rasterization Operator Units.Compare those specs to the Radeon HD 7850, which comes with core clock speeds of 860 MHz on the GPU, and 1200 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

BenchmarksThese are real-world performance benchmarks that were submitted by Hardware Compare users. The scores seen here are the average of all benchmarks submitted for each respective test and hardware.
3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7850 should be 7% faster than the GeForce GTX 660 overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 660 should be quite a bit (more or less 42%) more effective at texture filtering than the Radeon HD 7850. (explain)
Pixel RateThe Radeon HD 7850 is a little bit (about 17%) faster with regards to anti-aliasing than the GeForce GTX 660, and should be capable of handling higher screen resolutions while still performing well. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.

16 Responses to “GeForce GTX 660 vs Radeon HD 7850”i have sapphire 7850 2gb oc but gtx 660 better
evga gtx660 is alot better than 7850.Gtx660 beat 7850 easily
I bought the GTX 660 for 1366x768, and easily touched 60fps at all games
Can anyone ans is texal rate so important?
I have a 7850 OC. That's dumb. 660 is much and much better! Even for linux.
660 or 7850 oc...
is amd better on 1680 X 1080
as an engineer i'd say all those tests are more or less biased.
from a sticktly technical point of view hd7850 should be a much more powerful card
it's not only about the gpu /memory clocks
hd 7850 is much more customizable and OC-efficient.
I have the 660 and my friend has the 7850, when we compared frames on games such as bf3 and wow (using same processor) the 660 came out on top by about 5 fps
I think the saddest part about this benchmark is, AMD's 7850 is $100 cheaper.
gtx 660 is in stock better than the 7850 in stock clock, but when it comes to overclocking, the 7850 has a little advantage overall. Still nvidia has physx built in 🙂
me cago en tus muertos
i won the gtx 660 evga for the win signature 2 edition and its blazing fast.
Hi,im thinking on buying one of the two.And i just want to know which is better the gtx 660 or the 7850?
Which is better if I have AMD A10-5800k APU?
